tain chicle mixed with pontianak (sometimes 7 called gutta jelutong) and other gums, whose prmclpal purpose is to reduce the cost of the 10 -product, as chicle is very expensive compared with other gums. Ghicle and pontianak are both hard to obtain, as the trees producing them grow in diflicultly accessible areas of dense vegetation, and insteadof being tapped are often cut down and destroyed. Toda the cheaper chewing gums, such as unbran ed slot machine gums, contain ver little, if any, chicle, while the substitutes eretofore I available to replace part of the chicle in j 2 higher grade gums have been at times lacking in uniformit elasticity, resistance to oxidation, permanence of characteristics. under chewin and other properties which are def sirable m a chewing gum of good quality.

I have discovered 1n the coa ated latex obtained by tap in or extractlon from certain trees or husies, designated the .Euphorbia, an excellent chewing gum materiala so for a base or principal ingredient 0 an economical high grade chewing gum, and is in several respects superior to chicle. There are numerous species of the Eu horbia located in various parts of the worl and a5 supplying latex, which, according to my dis covery, is suitable for chewing purposes. I

have obtained excellent results with Euphor:

The latex of the uphorbia species which I have examined usually has a distinct acrid burnin taste, quickly noticeable in the 46 mouth and -t oat, but is rendered substantially tasteless when the acrid agent is removed.

- One method of debitterizing the Eu horbia coagulum is to treat it with alcoho but 50 my pre erred method is with an alkali such chewin This. coagulum is admirabl suited Central Africa, but- CHEWING GUM Application filed February 17. 1980. Serial No. 429,215.

Thegum is coagulated by heat or u other means,- and then manufactured into chewing gum, either by itself or preferably in combination with other ingredients and the usual flavoring materials.

' The following are examples of preferred gum compositions employing Euphor ia coagulum as the principal ingredient. The proportions given are percentage by weight, and the recipes are those of base compositions to which the usual-flavoring and sweetening materials are added .to produce finished chewing gum.

removed before manufacturing into chewing gum, entailing an expense which is eliminated when Euphorbia coagulum is used. Euphorbia coagulum also has a very smooth texture which is particularly desirable in a gum which comprises removing the bitter taste from Euphorbia coagulum, and mixing the debitterized gum with other palatable ingredients.

chewing gum, and in this respect is comparable with chicle and superior to pontianak.

Another desirable property of Euphorbia coagulum is that it does not oxidize readily.

This characteristic is especially desirable in a chewing gum after being put on sale, as the chewing gum containing a large proportion of Euphorbia coagulum is affected less by this treatment than gums containing the usual materials.

The methods of treatment and the various compositions mentioned above are simply intended as illustrative, and are not to be taken as limiting the invention, the scope of which is defined by the appended claims.

The invention claimed is:

1. A chewing gum comprising Euphorbia V coagulum.

2. A chewing gum comprising debitterized- Euphorbia coagulum.

3. A chewing gum base containing Euphorbia coagulum and other palatable ingredients in which the Euphorbia coagulum is present in preponderating amount. I
